Abstract :
In the paper, the conjugate gradient algorithm is introduced in detail and applied in system identification. After the problem of parameter estimation being transformed to a linear system equation, the problem can be solved by conjugate gradient iteration. Relative error of parameter identification is less than 0.1 percent. This simulation result shows its feasibility in parameter identification.
